Actually, you're not supposed to delete FLTK widgets with C++ delete,
FLTK must handle the deletion to ensure the widget(s) are properly
disconnected from the widget tree correctly.
I believe what you want is Fl::delete_widget() which will schedule
the deletion when you return to the application loop.

There should probably be a special section in the docs about
deleting widgets (if there isn't already one), as this seems to
come up a lot on the newsgroup.
